Abstract

The invented system T25J based on alternated motion that resulted from focusing the solar light thermal energy by parabolic mirrors on a two metal rods with two phases of heating /cooling process that will causing expansion /shrinkage energy. This alternated motion process that producing a mechanical energy that can be changed to others energy.

Description

Expansion/shrinkage Parabolic solar system
Technical Field: concentratesolar power CSP
Background Art: Parabolic trough
Disclosure of invention:The invention based on the thermal metal expansion /shrinkage that result when heating and cooling process applied to metal element producing big force and element expansion^
L) when heating and shrinkage(-A L)when cooling.
*1st is expansion, resulting by focusing the applied concentrated solar light energy along on a metal rod, to do expanding.
2nd shrinking, when it is cool by take it out from light focus point with injecting cooler liquid (water or any other heat transfer flowed).
When this alternatively heat/cool thermal applied process happened frequently for those two metal rods as applied mechanism that fixed in parabolic trough focus as shown in the drawings this will producing alternated two linear kinds of forces at same time, one rod give expansion force while the other will give shrinkage force.
Also we will get additional length, one rod will give expansion length at heating while the other does reverse action, itloss length at cooling.
Expansion length (AD :- Δ L= a Lo AT
Lo: initial length, AL: length increase, ΔΤ: change in temperature, a constant is called the average coefficient of linear expansion for a given material and has units of (° C) "\
Forcexfrom Young's Modulus
F= A.E. AL/I N
Hence Fe=Fs
Fs: shrinkage force. Fe: expansion force, F: the total gained force, E: Young's Modulus
Then Work done for only one element W
W=We+Ws= = 2F.AL
Power in watt (for one element) = 2F.AL ( ).... Watt or j/s
Power in watt (for two elements) = 4F.AL ( )... . Watt or j/s
Where We: expansion work, Ws: shrinkage work,
t=ts(shrinkage stroke time)+te( expansion stroke time).
Note:-
**The expansion/shrinkage metal element totally fixed at one side and move free at the other side to push/pull a hydraulic piston to transmit the produced forces either expansion force or shrinkage force to other energy conversion system.
**the available drawings in this submittal are just the major invention part just to clarify the invention idea.
**the system include automation to control all process metal rods elements turn over, suntracer and heat transfer flowed cycle for cooling to get shrinkage.
**there is hydraulic system that moving the trough for tracing the sun. Brief description of the drawing:
